Bug Description

Buildout should support setuptools' auto-packaging of single-.py dependencies in find-links, and from dependency_links. This is triggered by appending a "#egg=project-version" suffix to the url of the single .py file.

Currently, when I attempt to have buildout install a package with a .py#egg= dependency, buildout attempts and fails to locate a setup.py. For the moment I'm working around this by hosting my own eggs (auto-generated by easy_install -zmaxd.) of this dependency, but would rather not have to do this.
